I did a search for migraine aura on here, and didn't come across very much. I wondered if many other people have them, as I had thought they were pretty common in PWME. Any other thoughts on things that might help with them?
I experienced my first migraines within the first few months of developing ME. They were bad and came in a long series, and then they just went away. They were not preceded by aura.
About 4 years later, I had my first experience of a visual migraine aura (expanding, crescent-shaped, triangular-patterned "kaleidoscope" of light lasting about an hour). I would get them a couple of times a year, often 2 or 3 episodes just weeks apart, then nothing. Sometimes, there were years of "silence" between episodes. These events were never followed by a headache, but they would leave me feeling somewhat "out of it."
More frequently, I get a weird effects where a small, irregular dark spot rapidly appears in my visual field. It looks pretty similar to the aftereffect of a camera flash going off in you face (or the aftereffect of a brief look at the sun), but it lasts longer. Over about half an hour, the spot gets smaller, sometimes "dissolving" into smaller parts occupying the same space. There is no following headache.
I spoke to my ophthalmologist about this, and he said that this was also a form of visual migraine. I wonder if this could be triggered by allergy, because I've noticed that I am sometimes sneezing more around the time that I get these "flash bulb" effects in my vision.
Just curious if anyone has experienced something similar.
[FWIW: Technically, "ocular migraines," aka "retinal migraines," occur in the eye, whereas "visual migraines," or "ophthalmic migraines," occur in the brain. The terms are often confused. "Ocular migraines" produce a degree of temporary loss of vision in one eye and are considered more serious than "visual migraines." ]
